Stan is based on South Park creater Trey parker who also does his voice.

Stan Marsh is one of the four main characters in Southpark. Other three are Kenny Mccormick, Kyle Broflovski, and Eric Cartman.
Stan Marsh represents the average kid in America since he always gets pressured into situations that spin out of control(Episode F'ed in the A).
He basically says what everyday Americans are thinking in contraversial episodes thus he always ends up making up the moral at the end of the episode.

Randy: Stan listen to me. I don't want you to feel like you have to do that competition to avenge me.
Stan Marsh: Ok. Good.
Randy: I know i can't stop you from doing it so all i can say is... Give them Hell Son... Give them Hell.
Stan: God Damnit!
